Abstract
A shift register unit, a method of driving a shift register unit, a gate driving circuit, and a display device are disclosed. The shift register unit includes an input circuit and an output circuit. The input circuit is configured to write an input signal of the input terminal to the first node in response to an input control signal, so as to control a level of the first node. The output circuit is configured to receive a clock signal of the clock signal terminal and output a scanning signal through the pixel signal output terminal under control of the level of the first node. The output circuit includes a variable resistor, and the variable resistor is configured to adjust a level of the scanning signal according to a resistance value of the variable resistor.
